I don't think you are being serious now. Look at what I wrote.
You started by championing a sort (which is not bubble sort despite) the
just tested ~n**2 times an swapped as needed. You praised it's
memorability and it's locality in testing and swapping. So I showed you
an insertion sort that is more efficient, just as memorable, and also
has locality of testing and swapping. You've never discussed it because
it does not fit your narrative.
And when it became clear that insertion sort handles nearly sorted lists
"out of the box", you ditched the terrible sort you originally
championed and switched to actual bubble sort.

I don't need to see C code. I said I won't post sorting code in a
language unknown to me, that's all.

Don't be silly. Of course this is bubble sort (once the bug is removed)
and I never said otherwise. That's the whole point. It's not the
algorithm you started off championing.

You probably intended to compare data[i-1] and data[i], or maybe you
intended the loop to have different bounds, but one way or another
something is wrong here.

At this point you can decrease n (or otherwise adjust the loop upper
bound).
